  The appearance of a portable computing system, including its design and weight, is important to the user of the portable computing system. This is because the appearance contributes to the overall impression the user has about the portable computing system. At the same time, the assembly of portable computing systems is also important for users. This is because a durable assembly helps to extend the overall life of the portable computing system and increase its value to the user.

  One design challenge associated with the manufacture of portable computing systems is the design of the external enclosure that is used to house various internal computing components. This design challenge generally states that, among other possible goals, the outer enclosure or housing is lightweight and thin, the enclosure is strong, and the enclosure is aesthetically pleasing. Arises from a number of conflicting design goals, including demands. Lightweight housings or enclosures are more flexible and tend to collapse or bend, while strong and robust enclosures tend to be thicker and support greater weight. Unfortunately, the heavy weight does not provide user satisfaction with respect to coolness or difficulty in carrying, while bending can damage internal components and cause other failures. Moreover, few consumers desire to own or use devices that feel unsightly or uncomfortable. For such matters, enclosure materials for portable computing systems are typically selected to provide sufficient structural rigidity while meeting weight constraints, yet meeting their initial criteria. An aesthetic appeal is added to the material.

  Thus, the external enclosure or housing of a portable computing system is often made of aluminum, steel, and other inexpensive materials with appropriate thicknesses to achieve both the goals of low weight and high structural rigidity. But it is made of robust materials. The use of metal enclosures is also convenient in terms of providing a convenient electrical ground and / or a convenient radio frequency (RF) or electromagnetic interference (EMI) shield for the processor and other electrical components of the computing device. is there. This is because metal enclosures or outer housings can be easily used for such functions.

These examples are merely intended to add background and aid understanding of the present invention. Thus, it will be apparent to one skilled in the art that the present invention may be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail in order not to unnecessarily obscure the present invention. Other application examples are also conceivable and are not limited to the following examples.

  The following description relates to portable computing systems such as laptop computers, netbook computers, tablet computers, and the like. The portable computing system includes a multi-part housing having a top case and a bottom case that are joined together by a reveal to form a base part. The portable computing system also has a top (or lid) that can accommodate the display screen and other related components, while the base portion contains various processors, drivers, ports, batteries, keyboards, touchpads, etc. Accommodate. The base portion is formed of a multi-part housing that includes top and bottom outer housing components, each of which is formed in a specific manner in the interfacial region, and the gap and offset between those outer housing components can be In addition to being reduced, it is made more consistent from device to device. These general purposes are described in detail below.

  In a particular embodiment, the lid and base portion are pivotally attached to each other by what is referred to as a hollow clutch assembly. The hollow clutch assembly is configured to pivot the base portion to the lid. The hollow clutch assembly includes at least a hollow cylindrical portion including an annular outer region and a central bore region surrounded by the annular outer region, the central bore being between the base portion and the lid electrical component. Appropriately configured to provide a support for electrical conductors therebetween. The hollow clutch assembly also includes a plurality of fixed areas that couple the hollow clutch to the base portion and lid of the portable computing system, such that at least one of the fixed areas minimizes space, size, and parts count. In addition, it is formed integrally with the hollow cylindrical portion.

  The multi-part housing is formed of a strong, durable and lightweight material. Such materials include composite materials and / or metals such as aluminum. Aluminum has a number of properties that make it a good choice for multi-part housings. For example, aluminum is a good electrical conductor that provides a good electrical ground, is easy to process and has well-known metallurgical properties. In addition, aluminum is non-reactive and non-magnetic, which is an essential requirement when portable computing systems have RF capabilities such as WiFi, AM / FM, etc. In order to protect the multi-part housing and provide an aesthetically appealing finish (both visual and tactile), a protective layer can be disposed or formed on the outer surface of the multi-part housing. The protective layer can be applied in a manner that enhances the aesthetic appeal of the housing and protects the appearance of the portable computing system. In one embodiment, when the multi-part housing is formed of aluminum, at least the outer surface of the aluminum can be anodized to form a protective layer.

  The top case includes a cavity or lumen through which a plurality of motion components can be inserted during the assembly operation. In the described embodiment, in a “top-bottom” assembly operation where components are inserted in a top-down arrangement after first inserting the topmost component, the operational components are inserted into the lumen and attached to the top case. be able to. For example, a top case can be provided and shaped to accommodate the keyboard module. The keyboard module includes a keyboard assembly formed of a plurality of keycap assemblies and associated circuitry, eg, a flexible membrane that can incorporate a switching matrix. In one embodiment, the keycap assembly is as described in US patent application Ser. No. 12 / 712,102 entitled “STACKED METAL AND ELASTOMERIC DOME FOR KEY SWITCH” by Niu et al. It can take the form of a low profile keycap.

  In one embodiment, the keycap assembly can be used to replace a power switch. For example, in a conventional keyboard, at least one function can be specified for each keycap in the top row. However, by redeploying one of the keycaps as a power button, at least the switch mechanism associated with a conventional power button is eliminated and replaced with a keycap assembly and associated circuitry that is already available, thereby reducing the number of operating components. Can be reduced.

  In addition to the keyboard, portable computing systems include touch sensing devices along lines such as touchpads, touch screens, and the like. In embodiments where the portable computing device includes a touchpad, the touchpad is formed of a glass material. Glass material provides a decorative surface and is the primary source of structural rigidity for touchpads. Thus, the use of glass material significantly reduces the overall thickness of the touchpad compared to conventional designs. The touchpad can include circuitry for processing signals from both the sensor associated with the touchpad and the keyboard membrane associated with the keyboard. Thus, the separate circuitry conventionally used to process the signal from the keyboard membrane is eliminated.

  The touchpad includes a dome switch that detects operation of the touchpad covered with a seal mechanism. The dome switch includes an electrical switch. The sealing mechanism protects the electrical switch from ingress of dust and moisture and thus can improve the health of the electrical switch. The sealing mechanism can include an expansion gap where the dome switch expands when compressed. During operation, the use of the expansion gap improves the force feedback response associated with the dome switch and the overall aesthetic feel of the touchpad.

  In embodiments where at least one of the top case and the bottom case is formed of a conductive material such as aluminum, a good electrical ground plane or electrical ground can be provided. The ability to provide a good ground plane is particularly advantageous in portable computing systems because the operating components are in close proximity to each other. Because of this close proximity, it is desirable to isolate significant RF radiation sources (such as the main logic board or MLB) from circuits such as wireless circuits that are sensitive to RF interference. In this way, at least a conductive top case and / or bottom case is used to provide a good chassis ground, which is then used to move RF energy generating circuitry from RF energy sensitive components to electromagnetic Can be separated. Further, by forming both the top and bottom cases from conductive material, the top and bottom cases can be joined to effectively shield the external environment from EMI generated by the portable computing system. A base portion can be formed that serves as a cage). Attributes such as Faraday wrinkles in the base portion can also protect RF sensitive components from externally generated EMI.

  In order to give the user a satisfactory aesthetic, the shape of the portable computing system can have a satisfactory profile for eyes and touch. In the embodiments described herein, the multi-part housing can have a wedge shape. The wedge shape means that the angle provided by the wedge-shaped housing (especially the wedge-shaped upper portion of the multi-part housing) when the bottom surface of the portable computing system is placed on a flat support surface such as a table or desk is easy to use. An arrangement and a touchpad can be provided. In contrast to conventional portable computing systems such as laptop computers having a uniform shaped housing with little or no angle, the wedge shape of a portable computing system is a touchpad that aligns more naturally with the user's fingers. Providing a face and keycap can improve user interaction with the touchpad and keyboard. Such ergonomic improvements help to reduce the amount of stress and strain imposed on the user's wrist.

  At least because of the strong and resilient nature of the materials used to form the multi-part housing, the multi-part housing includes a large number of wide-span openings that do not require additional support structures. be able to. Such an opening takes the form of a port that can be used to provide access to internal circuitry. The port includes, for example, a data port suitable for accommodating a cable (USB, Ethernet (registered trademark), FireWire, etc.) for connecting an external circuit. The aperture can also provide access to audio circuitry, video display circuitry, power input, and the like.

  These and other embodiments are described below with reference to FIGS. However, it will be readily apparent to those skilled in the art that the detailed description set forth with reference to these drawings is merely illustrative, and that the invention extends beyond these limited embodiments. I will.

Portable Computing Device FIGS. 1-6 illustrate a portable computing system 100 according to embodiments described herein. FIG. 1 is a front perspective view of a portable computing system 100 in an open (lid) state, and FIG. 2 shows the portable computing system 100 in a closed (lid) state. The portable computing system 100 includes a base portion 102 formed by a bottom case 104 that is secured to a top case 106. The base portion 102 is pivotally attached to the lid portion 108 by a hollow clutch assembly 110 hidden from view by the decorative wall 111. Base portion 102 is generally wedge shaped and is sized to receive hollow clutch assembly 110 at its first end. The base portion 102 tapers to a narrower configuration end configured to accommodate an inset portion 112 suitable to help the user lift the lid portion 108 with, for example, a finger. In the embodiment described herein, the overall wedge-shaped appearance of the base portion 102 is created by the overall wedge shape of the top case 106. Alternatively, a wedge-shaped bottom case can give similar results. Top case 106 is configured to accommodate various user input devices such as keyboard 114 and touch pad 116. The keyboard 114 includes a plurality of low profile keycap assemblies each having an associated keypad 118.

  Each of the plurality of keypads 118 is imprinted with a symbol to identify key inputs associated with a particular keypad. The keyboard 114 is configured to receive individual inputs on each keypad using finger movements called keystrokes. In the embodiment described herein, each keypad symbol is laser etched to form a very clean and durable imprint that does not fade under conditions that always provide keystrokes over the life of the portable computing system 100. Is done. The touch pad 116 is configured to receive a user finger gesture. Finger gestures include touch events from hitting two or more fingers together. Gestures also include single finger touch events such as swipes or taps. To reduce the number of components, the keycap assembly can be re-prepared as a power button. For example, the keypad 118-1 can be used as the power button 118-1. In this way, the total number of components in the portable computing system 100 can be reduced proportionally.

  The lid portion 108 includes a display 120 and a rear cover 122 (shown more clearly in FIG. 2), which adds a decorative finish to the lid portion 108 and at least provides structural support for the display 120. In the embodiment described herein, the lid portion 108 includes a bezel 124 that surrounds the display 120. The lid portion 108 can be moved from the closed position with the help of the hollow clutch assembly 110, held in the open position, and returned again. The display 120 can display visual content such as a graphic user interface, still images such as photographs, and video media items such as movies. Display 120 may display images using a suitable technique such as a liquid crystal display (LCD), OLED, or the like. The portable computing system 100 also includes an image capture device 126 disposed on the bezel 124. The image capture device 126 is configured to capture both still images and video images. Display trim (or bezel) 124 may be supported by structural components (not shown) in lid portion 108 and attached to rear cover 122. Display trim 124 improves the overall appearance of display 120 by hiding motion and structural components and by focusing attention on the active area of display 120. Data ports 128 and 130 are used to transfer data and / or power between the external circuit (s) and portable computing system 100. The lid portion 108 is formed to have a unibody structure that provides additional strength and elasticity to the lid portion 108, which is particularly important due to the stress caused by repeated opening and closing. In addition to increased strength and elasticity, the unibody structure of the lid portion 108 can reduce the overall number of parts by eliminating individual support features.

Reference is made to FIGS. 3-6, which are side views of portable computing system 100. More particularly, FIG. 3 is a rear view of the portable computing system 100 with a cosmetic feature 111 used to conceal the hollow clutch assembly 110 and at least a support that can be used to support the portable computing system 100. Two support legs 132 are shown. The support legs 132 can be formed of a wear-resistant / elastic material such as plastic. FIG. 4 is a representative front view of the portable computing system 100 showing the relative position of the insert 112 between the top case 106 and the lid portion 108. A representative side view of the portable computing system 100, FIG. 5, shows the left side wall 134 of the top case 106 with openings that can be used to accommodate various data and power ports. For example, the opening 136 formed in the left side wall 134 can be used to accommodate an Ethernet cable, while the opening 138 can be used to accommodate a Magsafe ^™ receptacle 140. The opening 138 also has a high aspect ratio to accommodate the receptacle 140, due in part to a relatively large platform 142 or mesa that can easily align a properly configured power plug with respect to the receptacle 140. Note that you have to ask. In the particular embodiment described herein, an audio receptacle 144 and a side firing microphone 146 can be disposed on the sidewall 134. As shown in FIG. 6, the right side wall 148 of the top case 106 accommodates a data port 128 (such as a USB data port) and 130 that each take the form of a video port such as a DisplayPort ^™ type video port. The openings 150 and 152 used can be included.

  FIG. 7 is an external view of the bottom case 104, with the support legs 132, the insert 112, the exterior of the hollow clutch assembly 110, and a fixture 154 used to secure the bottom case 104 and the top case 106 together. The relative position of is shown. In the particular embodiment described herein, the fixture 154 can take the form of an anti-tamper fixture described in detail below. FIG. 8 is an internal view of the bottom case 104 showing the opening 156 used to accommodate the fixture 154. Further, the fixture 158 is used to secure the device leg 132 to the bottom case 104. The standoff 160 can be used to provide support for the bottom case 104 when the bottom case 104 is attached to the top case 106.

  FIGS. 9 a and 9 b show an exemplary embodiment of the top case 106. For example, FIG. 9a is an external view of the top case 106 showing the various openings used to accommodate the keyboard 114 and touchpad 116. FIG. More particularly, the openings 160 each have a size and shape based on a particular keycap assembly. For example, the opening 160-1 is sized to accommodate the power button 118-1, and the opening 160-2 is sized to accommodate the space bar. In addition to the opening 160, the opening 162 can support the touchpad 116. For example, the opening 162 includes an attachment feature 164 that is used to secure the touchpad 116 to the top case 106. In addition, a number of additional attachment features can be seen that can be used to secure both the touch pad 116 and the keyboard 114, as seen in FIG. 9b showing the interior of the top case 106. In certain embodiments, the keyboard 114 and touchpad 116 can share at least circuitry that can reduce the total number of components. Further, the notch 166 can be used in conjunction with the hollow clutch assembly 110 to give the portable computing system 100 a more integrated and integrated appearance. The attachment feature 168 can be used with the opening 156 to secure the bottom case 104 and the top case 106 with the use of suitable fasteners.

  FIGS. 10 a-10 c show the top case and feature plate assembly 180. FIG. 10a shows the entire assembly 180 in front perspective view, and FIG. 10b is an enlarged view of the corners of the assembly. As shown in FIG. 10 b, the feature plate 184 is secured to the top case 106 by a number of rivets 184. As will be readily apparent, a number of components can be placed between the feature plate 184 and the top case 106. FIG. 10c is a partial cross-sectional view of one rivet position of feature plate assembly 180, where riveting is performed in a composite beam format. For example, a feature plate 184, which is a thin steel plate, can be riveted at position 188 to an aluminum strap 186 placed between various keycaps (not shown). The strap 186 can then be coupled to the top case 106 or, in some embodiments, can be integrally formed with the top case. The location 188 is preferably sized and shaped to accommodate a rivet that travels through the proximity location of the feature plate 182.

  Numerous effects can be achieved by riveting the feature plate 182 to the top case 106 with multiple rivets 184 to enclose various internal components. For example, the top case 106 and the steel feature plate 182 can be combined to form an effective EMI shield, and in some embodiments, a Faraday saddle type shield can be formed. This EMI shielding effect is enhanced by using multiple fixing points held together by rivets, which uses the internal components of the keyboard using only a few fixing points, such as screw or bolt type configurations. Sometimes it tends to seal better. This EMI shield effectively isolates the keyboard in the EMI sense from various other components in the computing device, such as the processor or device antenna located directly below the keyboard.

  Another benefit is that the use of rivets rather than other types of fastening components such as screws, bolts, etc. allows the fastening components to be routed through the top case 106 or aluminum strap 186 to affect the strong fastening of the components. There is no need to extend it. This is effective when a smooth, uninterrupted surface is desired on the outside of the top case or on the aluminum strap. This also makes the manufacturing riveting process significantly faster than similar screwing or bolting processes in that, as mentioned above, in some cases it is not necessary to access the front side of the riveted component. This is also effective. Another benefit that can be realized by using rivets rather than screws is that the entire assembly can be thinned, especially since it is no longer necessary to accommodate threaded structures or components that require space.

  The use of rivets rather than screws or bolts tends to create a need for a large number of fastening components (ie rivets), but each rivet position is weaker than the position of each screw in a similar assembly. This tends to use a complex beam-type riveting configuration for increased strength and a quick riveting process to gain a smooth and uninterrupted front benefit on one side of the riveted assembly. It is countered by. The use of rivets rather than screws simplifies the manufacturing process, which saves cost, is fast, and allows more fixed points to be used, thus more reliably together Make fixed components more complete. The overall impression of the top case, keyboard and feature plate assembly riveted together is also improved by using rivets rather than screws. This is because the connection of the components tends to be harder, more stable and more strongly bonded as a whole assembly.

  FIG. 11 a shows an embodiment of a fastener 154 in the form of a tamper-proof fixture 170 that can be used to secure the bottom case 104 and the top case 106. In the embodiment described herein, the tamper-proof fixture 170 is formed to have a head 172 that includes a shaping indentation 174. The number and shape of the indentations 174 can vary widely. Thus, the only permitted mechanism that can engage the anti-tamper fixture 170 for insertion or removal is the driver 176 shown in FIG. 11b. Driver 176 includes a driver portion 178 shaped to correspond to shaping recess 174. In the specific implementation shown in FIGS. 11a and 11b, the tamper-proof fixture 170 includes five shaping indentations 174 (also referred to as lobes), and the tamper-proof fixture 170 is a pentalobe fixture. Also referred to as 170. Therefore, in order to properly engage the pentalobe fixture 170, the driver portion 178 of the driver 176 must have a shape that conforms to the pentalobe 174. In other words, driver portion 178 must be shaped and sized to match the shape and size of pentalobe 174. Accordingly, only individuals who have access to the authorized pentalobe 176 can properly engage the pentalobe fixture 170. Thus, the use of an inappropriately shaped driver can be easily detected because the pentalobe fixture 170 is likely to be damaged.

  FIG. 12 shows the portable computing system 100 with the bottom case 104 and battery removed to reveal various internal components and structures. For example, the fan assembly 602 is used to exhaust waste heat generated by the heat transfer module 604. The heat transfer or thermal module 604 includes stages 603 and 605. These stages 603 and 605 can thermally and mechanically couple the heat pipe 606 to heat generating components such as a central processing unit (CPU) and a graphics controller (GPU), respectively. In the illustrated embodiment, waste heat is transferred to the coolant (such as water) of the heat pipe 606 and conveyed to the fin stack 608. The fan assembly 602 then forces relatively cool air through the fin stack 608 to transfer heat from the coolant of the heat pipe 606 to the cold air and then exhausts the air through the rear vent 607. be able to.

  FIGS. 13a-13d are more detailed illustrations of an implementation of a thermal module 604 according to embodiments described herein. The thermal module 604 includes a spring stage 603 and a spring stage 605 that can contact the tops of the integrated circuit CPU and the GPU, respectively. Spring stages 603 and 605 have a substantially uniform thickness and act as stages and beams and springs. Stages 603 and 605 can provide an efficient thermal heat transfer path between the CPU and GPU and the heat pipe 606. The thermal module 604 has a low Z stack and is therefore well suited for compact computing systems. In order to provide an efficient thermal path, the stages 603 and 604 can be formed of a material with excellent thermal and mechanical properties. Excellent thermal properties can facilitate the transfer of heat from the CPU and GPU to the heat pipe 606. Excellent mechanical properties can ensure good mechanical coupling between the stages 603 and 605 and the CPU and GPU, respectively. More particularly, applying sufficient pressure to form a good mechanical / thermal interface can substantially improve the overall heat transfer characteristics of the thermal module 604.

  Returning to FIG. 12, audio circuitry 616 and 618 can be attached to the inner surface of the top case 106, which in one embodiment can carry audio from the portable computing device 100 via the keyboard 14. A touchpad / keyboard circuit 620 is connected to the MLB 612 by a flexible wire 622. The antenna cable 624 is secured to the top case 106 using a cable tie 626, while openings 628 and 630 (hereinafter referred to as hammerhead openings) assist in routing the cables 632 and 634, respectively. Become. Board to board connector 638 includes a ballast to prevent pin to pin shorts when the pins on board to board connector 638 are inserted into their corresponding openings.

  For example, as shown in FIGS. 14a and 14b, the board-to-board connector 638 has a number of pins 650 that can be inserted into mating openings 652 in the connector 654 as mating pairs. A plastic frame 656 can be provided to prevent angular displacement when the pin 650 is inserted into the opening 652. This plastic frame 656 can prevent angular misalignment. More particularly, a plow feature 658 at each end of the plastic frame 656 is placed in a corresponding slot 660 of the connector 654 to essentially create a half-piston in the connector 638 and the pin 650 is opened 652 prior to insertion. Align properly. In this way, the potentially damaging event can be prevented by coupling the plastic frame 656 to an existing component.

  FIG. 15 shows a specific implementation of openings 628 and 630 used to route cables 632 and 634. Openings 628 and 630 provide a deterministic way of assembling the cable and ensuring proper spatial placement and retention without adding parts. In the embodiment described herein, openings 628 and 630 are shaped similar to a hammerhead to accommodate cables 632 and 634. However, it should be noted that any suitable shape may be used. In this way, the cable dress (ie, efficient layout and aesthetic appearance) of the cable can be improved without depending on the addition of components. For example, the openings 628 and 630 in the MLB 612 can be provided by providing a well-defined path to the cable arrangement that helps reduce unnecessary cable routing and reduce both assembly time and cost. The cable routing can be subsidized.

  FIG. 16 is an enlarged view of region 700 of IPD circuit 640 that includes various keyboard and touchpad processing components. The processing component is the activation of a sensor, such as a membrane associated with the keyboard, and the position and / or change of the position of one or more objects on the top surface of the touchpad, eg, one or more fingers of the user. Is configured to receive a signal generated from the activation of one or more sensors associated with the touchpad 116, such as a dome switch. In one embodiment, the sensor can be formed from a PET material. The processing component is also adapted to accept a keyboard connector configured to communicate signals generated from user input received at the keyboard, eg, signals generated by actuation of membrane sensors associated with the keyboard. It may also include a configured keyboard interface. After processing, signals from the touchpad and / or keyboard are transmitted to the main logic board MLB 612 via the flexible line 622.

  17a and 17b show an exemplary cable strap 626 used to secure a cable such as the antenna cable 624 shown in FIG. In particular, certain cables are difficult to route due to their size and bend resistance, so providing a good cable dress for these types of cables is particularly applicable to the portable computing system 100. Small work areas are difficult and time consuming. Therefore, the cable strap 626 can provide an easy and efficient mechanism for rapidly routing and securing cables such as the antenna cable 624. The cable strap can take a number of forms suitable for a particular cable and location. For example, FIG. 17a shows a specific implementation of a cable strap in the form of a cable strap 626 (shown in FIG. 12) having a base portion 626 and a “tongue” portion 627 that can be used to route and secure the antenna cable 624. Show. As shown in FIG. 18, the base portion 626 of the cable strap 626 is first attached to the top case 106 and the antenna cable 624 to secure the antenna cable 624. With the bay portion 626 securely attached to the top case 106 to secure the antenna cable 624, the body portion 627 of the cable strap 626 is wrapped around the antenna cable 624 so that the tongue 627c is, for example, an adhesive To be fixed to the top case 106. In this way, the antenna cable 624 can be easily routed and secured with a simple and efficient operation suitable for an overall clean appearance that produces a good cable dress. FIG. 17 b shows another embodiment of a cable strap 626.

  FIG. 19 is an exploded view of a battery assembly 800 according to embodiments described herein. The battery assembly 800 includes a number of asymmetrical array of individual battery cells 802 surrounded by a frame as shown in detail in FIG. 20, and is a US patent entitled “INTEGRATED FRAME BATTERY CELL”, which is hereby incorporated by reference in its entirety. This is described in detail in application Ser. No. 12 / 714,737. Battery cell 800 is configured in a mirror image arrangement. For example, the battery cells 802a, 802b and 802c on the side 804 have corresponding battery cells 802a, 802b and 802c arranged in a mirror image arrangement on the side 806 of the battery assembly 800. In the embodiments described herein, the battery cell 802a has different characteristics than 802b or 802c, and vice versa. The battery 800 has a distributed battery management unit (BMU) or has individual BMUs as shown in FIG. In any case, by changing the size and characteristics of the battery cell 802, the battery 800 is arranged to have a low Z stack that matches the overall size and shape of the portable computing device 100.

High Speed Memory Card and Connector Returning to FIG. 12, the memory device 610 is used to store data as system main memory. The memory device 610 is a high-speed memory card and may take the form of a solid state memory device such as a flash memory that can be connected to a main logic board or other internal circuit such as the MLB 612 via a high-speed connector 614. In the described embodiment, the memory device 610 takes the form of a single layer of flash memory chips, and the number of memory chips is four in the described embodiment. However, it should be noted that any suitable number of memory chips can be used. In addition to the memory chip, one or more controller chips are also included. Memory device 610 is mounted on connector 614 by sliding contacts or pins 615 into connector 614 and then securing memory device 610 using a fixture through opening 617. In this manner, the reduced Z-stack of the memory device 610 can improve overall system integrity by allowing use of space that is not available in a conventional solid-state memory device. For example, the lateral stack arrangement of memory device 610 can be adapted to the space above system memory (not shown). In some embodiments, the memory device 610 may have a double-sided configuration that allows memory chips to be mounted on both sides of the memory device 610. This configuration is well suited for computing systems that have slightly more space available than the particular embodiment shown in FIG.

  21a-21d are perspective, side, bottom, and top views, respectively, illustrating an SSD memory module 610 according to embodiments described herein. As described above, the SSD memory module 610 includes the memory chip 611 on one side, while in other embodiments, the memory chip can be disposed on both sides of the SSD memory module 610. Again, one or more controller chips 613 can be used, and the card 61 can also include one or more insulator regions 619. In the illustrated embodiment, the SSD memory module 610 is arranged in a “stick of gum” configuration in which the active components of the SSD memory module 610 are arranged in a lateral configuration. In this manner, the SSD memory module 610 has a low Z stack and can therefore be placed in the portable computing device 100 in areas not available with conventional solid state memory. In particular, if the number of components is minimized and the components are arranged in a space efficient manner, the SSD memory module 610 can be housed in the area directly above the CPU memory to form an area with a high component packing density. .

  Although a variety of shapes, sizes and dimensions can be used for such a high speed SSD memory module 610, various specific dimensions provide context for the specific example shown in FIGS. 12 and 21a-21d. For example, the memory module or card 610 has a total length (including contacts / pins) of about 108-110 mm, a width of about 23-25 mm, and a board thickness of about 0.6-0.8 mm. More specifically, the memory module or card 610 has an overall length of about 108.9 mm, a width of about 24 mm, and a board thickness of about 0.7 mm. The maximum thickness of the memory chip or other component placed on the board is about 1.4 mm at most locations on the card, but a reduced maximum thickness is applied near the edge of the board. The maximum composite thickness of the module at all positions is about 2.2 mm. The opening 617 is a semicircle having a diameter of about 6 mm.

  Turning now to FIG. 22a, another SSD memory module having memory chips on both sides is shown in side view. The SSD memory module or card 610a is substantially similar to the card 610, but the memory chip 611 can be included on both sides of the card. All such memory chips on both sides of the module are routed to a set of contacts or pins 615 located on one edge of the SSD memory module.

  FIG. 22b is an enlarged view of the contacts of the SSD memory module according to the embodiments described herein. Again, the SSD memory module or card 610 includes one or more insulator regions 619 and a set of contacts 615 disposed on one edge of the card surface. In some embodiments, exactly 18 contacts 615 are used, but it will be readily apparent that more or fewer contacts may be used in a given application. In the particular embodiment shown here, 18 contacts are divided into a first part consisting of 6 contacts and a second part consisting of 12 contacts. These first and second portions or groups of contacts are separated by a physical gap 615-0 that is used to help facilitate proper insertion of the module into each connector. For example, the gap 615-0 is positioned to fit around a post or other physical stopper in the connector structure so that attempts to insert the memory module 610 backwards will not succeed.

他の接点配列及び機能も確かに可能であるが、以上の特定の構成は、ここに開示する特定のポータブルコンピューティングシステムに対して充分に作用すると考えられる。 In the particular embodiment shown here, each of the contacts or pins 615 has a specific purpose or function. For example, starting from the first contact at the bottom of the second part of twelve contacts, each contact has a specific function as follows.

While other contact arrangements and functions are certainly possible, the above specific configurations are believed to work well for the specific portable computing systems disclosed herein.

  FIG. 23 is a top perspective view showing various details regarding a high speed connector for use in the SSD memory module. This figure, like the other figures included, is for illustration and is not intended to limit the possible embodiments of the invention or the claims.

  A connector 1100 that is identical or substantially similar to the connector 614 generally described above includes an insulating housing 1110, a plurality of contacts 1120, and a shield 1130. This connector is mounted on a printed circuit board. The printed circuit board is a motherboard, main board, multilayer board, or other type of board. Connector 1100 is adapted to receive a card or board, eg, a daughter or any card or board.

  Insulative housing 1110 includes a front opening 1112 for receiving a daughter or any card. Insulating housing 1110 also includes one or more openings 1114 shown in the top surface of insulating housing 1110 in this example. These one or more openings 1114 are used to visually or otherwise determine that the card has been properly inserted into connector 1100.

  In this example, each of the plurality of contacts 1120 includes a first portion 1122 and a second portion 1124. The first portion 1122 extends away from the front surface of the housing 1110. The first portion 1122 is used to contact a contact or pad disposed on the printed circuit board. The second portion 1124 is substantially in line with the first portion. The second portion 1124 contacts the contact on the card when the card is inserted into the connector 1100. Each of the contacts 1120 also includes a third portion (not shown) for mechanical stability, as described below.

  The shield 1130 covers at least the top and back of the connector 1100. The shield 1130 is used as a ground plane and is connected to one or more ground contacts on the card and one or more ground contacts on the printed circuit board. The shield 1130 is divided into two or more parts. In this particular example, shield 1130 is divided into three parts. Dividing the shield 1130 into portions provides the shield 1130 with the shield 1130 by ensuring that the shield 1130 is in contact with the ground contact of the card at three or more points when the card is inserted into the connector 1100. Improve grounding. In this particular example, one or more portions 1132 of shield 1130 are folded under the top of shield 1130. In this configuration, when a card is inserted into the opening 1112 of the connector 1100, the shield portion 1132 pushes against the top surface of the card, thereby engaging one or more ground contacts. This action also pushes the contact on the card to the second portion 1124 of the contact 1120 to form an electrical path. A tab 1134 is disposed on the shield 1130 and is used to connect the shield 1130 to the ground point of the printed circuit board.

  Embodiments of the present invention provide a connector having a high speed path between a daughter or any card and a printed circuit board. More specifically, the first portion 1122 and the second portion 1124 of the contact 1120 form a short direct path through which one or more signals and power are sent. These paths are also shielded by shield 1130 to improve signal quality and allow faster data rates. Dividing the shield 1130 into multiple portions improves the ground connection between the ground point on the card and the ground point on the shield.

  Further, the short direct path formed by the contacts 1120 can make the connector 1100 low. The third portion of contact 1120 is used to provide mechanical stability. This third portion is substantially in line with the first portion 1122 and is parallel to the bottom of the connector 1100.

  Embodiments of the present invention provide a connector that improves the reliability of the manufacturing process. More specifically, the first portion 1122 is a surface mount contact. These first portions 1122 are soldered to pads or contacts on the printed circuit board. This allows easy inspection of the solder connection of the contacts 1122 to the printed circuit board. The opening 1114 also allows inspection to ensure that the card is properly inserted into the connector 1100.

  FIG. 24 is a bottom perspective view of a connector 1100 according to an embodiment described herein. This view includes an insulating housing 1110, a plurality of contacts 1120, and a shield 1130. The insulating housing 1110 includes a tab 1140. These tabs are used to provide mechanical support for the connector 1100 on the printed circuit board. Tab 134 is used to make an electrical connection between shield 1130 and a ground line or plane on the printed circuit board. In various embodiments, the housing 1110 is plastic or other insulating material. Contact 1120 is stainless steel, copper, brass, aluminum or other conductive material. Similarly, shield 1130 is stainless steel, copper, brass, aluminum, or other conductive material.

  In this particular example, 18 contacts are shown, but again, other numbers of contacts may be used. Also, although the first portion 1122 is shown extending from the front surface of the contact 1100, in other embodiments of the invention they may extend in other directions. For example, they may extend downward or may extend toward the back of the connector 1100. In other embodiments of the present invention, the first portion 1122 and the second portion 1124 of the contact 1120 may be the same portion. Further, although the shield 1130 is shown as having a particular configuration, other configurations are also contemplated. For example, the shield 1130 is not divided into multiple portions, but in other embodiments of the invention, the shield 1130 is divided into two or more portions. Also, although one or more openings 1114 are shown at the top of the insulating housing 1110, in other embodiments, these openings may be omitted and there may be more or less than two openings 1140. Alternatively, the opening may be provided anywhere. Again, the connector 1100 may accept or accept a daughter or any card, one example being shown in the accompanying drawings.

  FIG. 25 is a diagram illustrating a daughter or optional card inserted into a connector according to embodiments described herein. This example includes a connector 1300 that accepts a daughter or any card 1360. The card 1360 is the same or substantially similar to the SSD memory module 610 or 610a detailed above. When card 1360 is inserted into connector 1300, the contact at the top of card 1360 forms an electrical connection with portion 1332 of shield 1330. The contacts at the bottom of card 1360 form an electrical connection with second portion 1324 of contacts 1320. Again, various embodiments provide a very short signal path from the card 1310 to the printed circuit board on which the connector 1300 resides. More specifically, the signal path includes a first portion 1322 and a second portion 1324 of the contact 1320. Contact 1320 also provides mechanical stability by including third portion 1326. More specifically, the third portion 1326 extends to the insulating housing 1310. In this example, the second portion 1324 and the third portion 1326 extend to the insulating housing 1310, while the first portion 1322 extends away from the front surface of the connector 1300. The second portion 1324 and the third portion 1326 of the contact 1320 are substantially in line with the first portion 1322. Third portion 1326 extends substantially parallel to the bottom of connector 1300.

  26 is a top view of the connector, and FIG. 27 is a cross-sectional view of the connector receptacle of FIG. 26 taken along line FF. A contact 1322 and shield 1332 according to one embodiment of the invention are shown in cross-section. FIG. 28 shows a detail region G from FIG. 26 of a portion of the top of the connector according to the embodiments described herein. As shown, the physical stop 1350 can be used to separate the contacts into groups. Also, as described above, the physical stopper 1350 is arranged to mate with the associated memory card gap 615-0 to prevent the memory card from being inserted backwards into the connector.

  FIG. 29 is a front view of a connector according to an embodiment described herein. FIG. 30 is a side view of a connector according to an embodiment described herein. FIG. 31 shows a detail area E from FIG. 30 of the side view of the connector according to the embodiment described herein. FIG. 32 is a bottom view of a connector according to an embodiment described herein.

  Again, these examples illustrate embodiments of the invention. Changes to these connector parts, such as the insulating housing 110, the contacts 120, the shield 130, and portions thereof, can be made consistent with embodiments of the present invention, in which the connector according to the present invention is suitably Note that nothing needs to have the specific shape, size, arrangement, or other characteristics shown to function.

  FIG. 33 is a flowchart detailing a process according to an embodiment described herein. Process 3300 begins at 3302 by providing a bottom case and a top case, at least one of which is wedge shaped. At 3304, the bottom case is coupled to the top case to form a complete housing of the base portion of the portable computing device for enclosing at least the plurality of operational components and the plurality of structural components. The base portion defines a wedge shape such that one or more user input components are presented at an angle to the user of the portable computing device, the wedge shape having a wedge shape on the top or bottom case. It is a result. At 3306, the base portion is pivotally attached to the lid portion by a hinge assembly. In the embodiments described herein, the lid portion has a plurality of components, at least one of which is a display. At 3308, at least some of the components of the lid portion are electrically connected to the operating components of the base portion by one or more electrical conductors extending through the hinge assembly.

  Although the invention has been illustrated and described in detail for purposes of clarity and understanding, it should be understood that the invention can be practiced in many other ways without departing from the spirit or essential characteristics thereof. Since numerous changes and modifications can be made, the invention is not limited to the above description, but only by the claims.
